It seems I can get rid of FPICFLAGS -fno-common and CPPFLAGS  
-D__DEBUGGING__

If you do not use -lcc_dynamic as LDFLAGS it cannot find restFP and  
saveFP.
/usr/lib/libcc_dynamic.a is a soft link to  
/usr/lib/gcc/darwin/3.3/libgcc.a
which does contain these symbols.

By the way, the symbols are not in  
/usr/local/lib/gcc/powerpc-apple-darwin6.6/3.4/libgcc.a

Also, configure tests if saveFP is in libcc_dynamic.a, and says it  
isn't.

we are trying to adapt the configure in order to work with latest  
gcc3.3 (from apple) and g77 3.4 (from  
http://gravity.psu.edu/~khanna/hpc.html )
At the moment there is no need to define the __DEBUGGING__ but there  
is still a problem with the -lcc_dynamic

does any of you know how to check for this library and explain why we  
see -lcc_dynamic often passed as an ld flag.
Where to find doc on this?

R-devel configs and build fine on both configurations below.
It would be nice to test it on Panther eventually. A great thank goes 
from my side to Kurt for this configure version.

I configure with:

./configure --enable-R-shlib --with-blas='-framework vecLib' 
--with-lapack 
--with-tcl-config=/Library/Frameworks/Tcl.framework/tclConfig.sh 
--with-tk-config=/Library/Frameworks/Tk.framework/tkConfig.sh 
--with-aqua

and you should eventually change the tcl/tk config files

I'll update the instructions on the webpage for RAqua.
